COMBINED MOP HEAD AND WRINGER.

SPECIFICATION forming part of Letters Patent No. 787,890, dated April 25, 1905.

Application filed May 8, 1903. Serial No. 156,276.

To 07/ 11410111 it may concern:

Be it known that I, (,nA'nLns R. Canrnx'rm-z, a citizen of the United States, residing at Racine, county of Racine, \Visconsin, have invented certain new and useful Improvements in a Combined .\Iop Head and \Vringer; and 1 do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to certain improvements in mops, and more particularly to improvements in combined mop heads and wringers; and the objects and nature of my invention will be readily understood by those skilled in the art in the light of the following explanations of the constructions shown in the accompanying drawings merely as examples from among other arrangements within the spirit and scope of my invention.

My invention consists in certain novel features of construction and in combinations and arrangements of parts, as more fully and particularly set forth and specified hereinafter.

Referring to the accompanying drawings, Figure 1 is a perspective view of the mophead, the mop-cloth not beingshown to avoid hiding parts, the deflector and water-shed being shown provided with bristles to form a scrubbrush. Fig. 2 is a top plan view showing the mop-cloth in position. Fig. 3 is a longitudinal sectional view showing the crankroller and the pressu re-roller in end elevation, arrows indicating the direction of movement of the mop-cloth when being wrung, the water forced from the cloth and deflected by the water-shed being indicated, the water-shed being shown without the bristles. Fig. i is an edge elevation of the mop-head. Fig. 5 is an ed elevation showing a modified arrangement of bearing sockets or depressions for the journals of the crank-roll and a somewhat different arrangement of the pressure-roll with respect to the crank-roll. Fig. 6 is a detail view showing how the pressure-roll is gripped and held by its spring when the crankroll and mop-cloth are removed.

In the drawings, a is the handle of the mop. This handle is secured in any suitable manner to the mop head or frame, which extends downwardly therefrom. [n the specific example illustrated the mop head or frame is formed with a central upwardly-projecting socket f; to receive the handle a and in which the handle is secured. This socket is shown extending up from the top transverse crossbar of a U-shaped depending metal frame. This frame is composed of said cross-bar and the depending parallel side bars v, formed with the forwardly and horizontally elongated vertical side or guide plates r/, at their lower edges having the horizontal flanges r3, resting on aml secured to the transverse block or plate f by screws or other suitable fastening means. The socket I), as shown, is formed with the laterally-extending handholds 1 one of which is shown extended and slotted to form a catch /r to hold the crimk-hamlle of the crank-roll in locked position against rotation. in the specific example illustrated 1 form the frame with its socket and handholds in one piece of metal, usually by casting.

is the crank or wringer-roll arranged a short distance above and parallel with the plate or block f and extending between the lower portions of the side bars of said U- shaped frame, so as to leave a sufficient space between said roll and the top surface of plate or block f for the free passage of one ply of the endless thick fabric mop-cloth j, which passes over said roll. This roll is formed or provided with outwardly-projecting end pintles or journals fi', rigid with the roll. is a crank-handle at one end rigidly secured to the outer projecting end of one of the pintles k. This handle is provided to rotate the said roll and the endless mop-cloth, and it is arranged outside of the mop head or frame and is normally held by the catch /1 to lock the said roll against rotation. The crankhamlle is sufficiently flexible to permit its being sprung into and out of locking engagement with said catch. As it is desirable that the said roll carrying the endless mop-cloth be readily removable from the mop-head, although as at present advised 1 do not wish to so limit all features of my invention, 1 provide the said side bars of the frame with bearing sockets or depressions 11/, extending inwardly through the front edges of said side from when the mop-cloth is removed.

bars and open at their front ends. The depth of each socket or depression m is preferably greater than the diameter of the pintle Z2, and said bearing-sockets are so formed that the said pintles will rest and turn therein and so that the said roll can be readily dropped into the frame from the front with its pintles entering said depressions and can be readily removed by pulling or forcing the same for wardly from the frame. The bearing sockets or depressions can extend directly inwardly transversely of the side bars of the frame, as shown in Fig. 4, or said sockets or depressions can extend downwardly and inwardly at an angle, about as shown at m, Fig. 5. WVith either construction the crank-roll is yieldingly and normally confined in operative position in the mop-head by the upper pressure-roll n. This roll at is arranged above and parallel with the crank-roll and is located between the side bars of the frame. This pressure-roll is formed with the end journals or pintles 0 arranged within the frame and preferably with their outer ends terminating a short distance from the inner faces of the side bars of the frame. This pressure-roll is maintained in position and forcibly and yieldingly held toward the crank-roll and compressing the mopcloth between the two rolls by a plate-spring arranged longitudinally of the under side of the top cross-bar of the U-shaped frame and at its intermediate portion rigidly secured to the central portion of said cross-bar with the free ends of the spring constantly pressing downwardly against the pintles 0 of the pressure-roll and forcing said roll with the necessary pressure against the mop-cloth. The free ends of said spring are bent to form the vertical portions (1 between the ends of the pressure-roller and the inner faces of the side bars of the frame, and the lower edges of these free ends of the spring are notched or recessed to receive the pintles of the pressure roll. These notches open down wardly, so that the pressure-roll can be removed from the spring ends, if desired, after the crank-roll and mop-cloth have been removed from the mop-head. The ends of the spring are so arranged that when the pressure-roll is in its normal operative position compressing the mopcloth on the crank-roll the ends q will be pressed upwardly and outwardly from the end faces of the pressure-roll; but when the crankroll and mop-cloth are removed the pressureroll is forced downwardly by the spring, thereby causing the ends of the spring to move down and the portions 11 of the ends of the spring to move toward each other and bear against the end faces of the pressure-roll, thereby gripping or clamping said roll and holding it in the mop-head and against dropping there- It will hence be observed that the pressure-roll is, in effect, mounted in and carried by its spring and is maintained in proper position in the mop-head by the spring when the crank-roll and mop-cloth are removed, notwithstanding the fact that the pressure-roll is itself removable. The pressure-roll is so arranged with respect to the crank-roll that the pressure of the spring maintains the pintles of the crankroll in the open bearing-sockets of the side bars while the mop is in use and while the rolls are being rotated to wring the mopcloth.

In the construction shown in Fig. 5 the axes of the two rolls are approximately in the same plane with the U-shaped frame and the handle, so that the pressure of the spring holds the crank-roll pintles down into the recessed lower portions of the bearing-sockets. In this construction the crank-roll can be removed by reversing the mop and jerking downwardly on the mop-cloth to force the crank-roll downwardly and out of the sockets.

In the arrangement shown in other views of the drawings the pressure-roll is shown arranged in a plane slightly in advance of the plane of the frame and axis of the crank-roll, so as to normally hold the crank-roll against outward movement and maintain its pintles at the inner ends of the open sockets m. In this construction the crank-roll and mop-cloth can be removed by forcing the crank-roll directly outwardly, which will cause the pressure-roll to move up against its spring sufficiently to permit the outward passage of the crank-roll from the frame.

The side bars of the U-shaped frame preferably extend upwardly and rearwardly from the upper rear corners of and at an angle to the vertical guide-plates (Z, and said guideplates extend forwardly transversely across the ends of the block or plate f. The crankroll is preferably arranged above the longitudinal rear edge portion of the plate or block f, so that the lower ply of the endless mopcloth passes from the under surface of the crank-roll forwardly and transversely across the upper face of the plate f, between the elongated guides cl, and hangs from the front longitudinal edge of said plate f. 'When the mop-head is held in operative position for wringing the mop-cloth, the upper face of the plate f is preferably inclined slightly downwardly and rear-wardly, (see Fig. 3,) so that when the crank-roll is rotated in the direction of the arrow the under ply of the mop-cloth will travel upwardly to the front edge of the plate f and rearwardly across the top face of said plate and upwardly at the rear of the cranl roll and forwardly between the two rolls. The water is squeezed and wrung from the mop-cloth and falls at the rear of the crankroll onto the plate f and is deflected thereby from the mop-cloth and discharged at the rear edge of the plate f. The plate f thus forms a deflector or water-shed, keeping the water from the mop-cloth and enabling the operator to thoroughly wring the mop-cloth by a few turns of the crank-handle. The deflector or water-shed f, arranged approximately as described with respect to the mop-cloth, permits the employment of an endless mop-cloth and permits the efficient wringing of the endless mop-cloth by preventing the water wrung from the cloth from running down the length of the endless cloth. The guide'plates (Z engage the edges of the lower ply of the mopcloth for a considerable distance in advance of the crank-roll and effectively maintain said cloth in the proper position with respect to the rolls and prevent doubling of the edges of the cloth and the cloth from working edgewise longitudinally of the rolls.

\Vhen the mop is in use, the mop-cloth can be forced and held to the floor or other surface with the desired pressure by the plate or hlockf, as the mop-cloth can pass under the bottom face of said plate or under the edge thereof.

The plate or block f can be formed by the back or body of a SUlLlb-blLlSl'l, as shown in Fig. 2, or can be composed of a plain block or plate, as shown in other figures of the drawings, as the brush is not essential to the operation of the device when employed solely as a mop. However, the usefulness of the device is increased by including the scrubbrush, and I prefer to employ the same.

The terms water shed, deflector, plate, and block are employed herein in a broad sense in referring to the member f, whether or not said member is used in connection with bristles or a scrub-brush.

It evident that various changes might be made in the forms, constructions, and arrangements of the parts described without departing from the spirit and scope of my invention. Hence I do not wish to limit my invention to the constructions shown, but consider myself entitled to all such changes as fall within the spirit and scope of my invention.
